I don't know about eBay US. But, am happily using my HTC Desire from eBay UK (unlocked from T-Mobile), bought 2 years back. There was no issues with shipping or their unlocking. That time I paid around 24k upfront, and even I was afraid of how it will be. But luckily it was very smooth. Got in 1 week. You may better check with the dealer mentioned in that link regarding the Item Condition/Shipment.
